Abstract
A heat-sensitive recording material and a recording method are disclosed, wherein the heat-sensitive recording material comprises a support having formed thereon plural heat-coloring elements each comprising a diazo compound and a coupling component capable of causing heat-coloring, the heat-coloring elements coloring in two or more different hues, and the coloring property in each heat-coloring element being capable of being stopped by the action of different radiations, and the recording method comprises first heat-coloring a heat-coloring element of the heat-sensitive recording material, stopping the heat-coloring property of the uncolored portions of the first heat-coloring element by radiation, and then heat-coloring another heat-coloring element; wherein the recording method comprises applying two or more heat-coloring procedures and one or more irradiations of radiation to form recorded images composed of two or more colors on the same sheet.
